Ok, a probability question. You have 4 darts and 3 possible values. It's a combination since the order of the darts doesn't matter.

Do you know factorial notation?

Factorial is multiplying a number, then multiplying by one less, and it continues down to 1. So 4! is 4*3*2*1, and 1! is 1. 4*3*2*1 also happens to be your answer.

So 10010 is 90. What is 20 percent of 90?

Yep. 9018 is 72. So 10072 is your total discount.
